The world's most powerful rocket has successfully blasted off in to the heavens on its first test flight.
The Falcon Heavy, which consists of a strengthened Falcon 9 rocket core with two additional Falcon 9 boosters on either side, soared high in to the sky above Cape Canaveral, Florida today after a truly spectacular launch from the historic 39A pad at NASA's Kennedy Space Center.
Not only did the launch itself succeed, but both side boosters came back in to land, side by side, in a highly impressive and controlled descent that saw them touch down within 1,000ft of one another.
The rocket even managed to deliver its payload - Elon Musk's Tesla Roadster - in to space where it was filmed against the backdrop of the Earth with a David Bowie song playing in the background.
The full stream of the event can be viewed below. ( skip to 28:00 for the actual launch )
What doesn't sound right? That there are many rocket stages in orbit around the Sun? Every probe that travels to a planet, comet etc. needs to be accelerated to beyond Earth's escape velocity using a rocket stage. These stages go into orbit around the Sun. Here is a link to a Wiki page which gives some idea of how many have been launched during the last fifty-odd years. https://en.wikipedia.org/wiki/List_of_Solar_System_probes You can count them yourself!
I meant no offence: I was simply meaning that if you want to know how many rocket stages, probes, and other human-made objects are in orbit around the Sun, you can count them yourself.
No worries. I definitely need to read up on how the rockets work, stages during the flight, etc at some point in time. Most of my knowledge comes from watching Apollo 13. Oh and regarding the orbit thing: Something has to be specifically 'set' in orbit, right? So it didn't make sense to me that rocket stages or probes would consistently drop into orbit solely around the sun. But after checking out mercs link I see how heliocentric is different from what I was thinking. If heliocentric is redundant in this context then my bad.
An orbit is simply the path an object follows under the influence of a gravitational field. We tend to think of orbits as being "closed", as in an ellipse or a circle (which is really just a special case of an ellipse). This is because the word "orbit" is derived from "orb" - ancient people used to think that the Sun, Moon, planets and stars were embedded on a series of moving glass orbs (spheres) all centered on the Earth. There are also "open" orbits, which are parabolic or hyperbolic. Whether an orbit is closed or open depends on the velocity of the object in question, and the strength ... [More]
